Full Throttle Contact Functions
When the full throttle contact closes (closed from throttle gap) at approximately 135°F (66°C), the mixture is richened and the ignition timing corrected to full throttle performance. When closed, the throttle switch connects ground (negative) to the LH-Jetronic and the EZF ignition control unit. To enable the throttle switch to be checked, there is a plug connection on the right side next to the oil filler neck. See Fig 1 .
